I bought this lecture series for help with learning to meditate. I did not find it too helpful on that front as I am a complete beginner and the lecturer did not take the sort of hand-holding approach to meditation that I feel I need.
BUT, the lectures that dealt with topics related to meditation and not meditation itself were amazing. I think they've helped me unlock the key mysteries about myself and my interactions with others and things that I've been struggling with for a great many years. I'm very, very glad I bought and listened to these lectures.
